SUBJECT: Dry and cold 11月 finishes strange fall
圣人云 11月 2002 and fall weather summary
The October weather pattern continued in 11月. While the persistent air flow from the 育空河 生产 圣人云's second coldest October on record, we ended up with slightly above normal temperatures for 11月. 根据 圣人云 市政 机场 statistics, the average temperature was 29.8 degrees, a degree above normal.
The main news of 11月 2002 was the dry weather. 育空河 air contains very little moisture and both the 11月 precipitation (0.11 inch) and the 11月 snowfall (0.4 inch) demonstrated the dominance of Canadian air. This made 11月 2002 the driest 11月 in 61 年 and the 7th driest 11月 in 圣人云 历史. The snowfall total marked only the 5th 11月 in the past 50 年 in which there was half an inch or less. The last time this happened was 1981. Despite the dryness, 圣人云’s total rainfall for 2002 has now reached 34.94 inches, which ranks as the 第10个最湿年份 in 圣人云 历史 with December still to go.
圣人云’s fall (September 1-11月 30) statistics are proof of the adage, “数字不会说谎, 但是骗子肯定会说.”
前方是什么?? Well, the 国家气象局 has its official winter forecast out (can be found at http://www.cpc.ncep.noaa.gov/). According to this forecast, Minnesota has the best chance of anywhere in the country for a mild winter. The reason for this forecast is the development of El Nino, the anomalous warm ocean condition in the Tropical Pacific (for more, 看到 http://www.crh.noaa.gov/女性性功能障碍/前景.htm). However, I look at the weather pattern that we’ve been stuck in for the past 7 weeks and say, “Ha!”
As long as that persistent high stays in British Columbia, our air will continue to come from the Northwest Territories. My only question is whether our temperatures will be near normal or below normal. That depends on how quickly we get snow cover. Snow reflects most of the sun’s energy back to space. 没有它, the cold air masses are being warmed more than the usual as they pass over the bare ground over the Northern Plains and much of the adjacent Canadian Prairie Provinces. That factor has kept the temperature from being able to drop below zero during our cold blasts. This northerly flow pattern is very dry pattern so, to get a storm system to produce snow, it will have to pass through Minnesota to the south of 圣人云. During the past month, nearly every storm has stayed well to our north, leaving us high and dry. So, that’s the only uncertain point in my mind. 否则, I think we can expect a winter with below normal snowfall and normal to below normal temperatures.
